To allwhom it may concern.' I.

Be it knownthat I, THOMAS M. DEVANNEY,

a citizen of the United States Of` America,

and resident of Cincinnati, county of Ham-- vcounter support plate in which means are provided for decreasing the wear occasioned by the passage of the roller across the plate, during the counter finishing operation.'

This and other Objects I attain by means of a machine combining the features herein described, and illustrated in the drawings accompanying and forming a part of this application.

In the drawings Figure 1 is a side'elevation of acount'er nishing machine embodyj vided with a central openmg 12, asis customing my invention, with portions shown in section for convenience of illust-ration.

Fig. 2 is a perspective view vof acounter support plate forming a detail of my invention.

Fig. 3 is a section along theline 3 3 of Fig.- 2, shown ill-connection with la Ifragmental section of the table on which the lplate is mounted.

Fig. 4 is a corresponding view along the line 4'.-4 of Fig; 2.

Fig. 5 is 'a sectional view taken yon the lline 5-5 of Fig. V1. y

The machine illustrated includes a frame 5, a movable table 6 mounted on the frame, and a finishing or grinding roll 7 ljournaled on the frame. The table is capable of moving back andforth beneath'the roll, for the purpose of moving a shoe counter, carried by it, into engagement withtheroll. A counter support plate `8is mounted onethe table substantially as follows:

and 'is provided with v a central depression, over which thecounter is located, during the grinding or finishing operation. The ma-l chine is also provided with the -usual clamp v 9, which automatically engages the edge of a counter on the'support plate, as the table moves inwardly toward the grinding roll,

ground by the roll and so that the counter Specification of Iietters Patent.

may. be deliveredlfrom the machinev after 1t 1s finished. Y

' A machine having an -ordinary counter support plate is objectionable, since the surface of the plate is engaged by the finishing roll 7 during the forward motion of the plate, and consequently, it, as well as the counter, is subjected to the grinding action of the roll. This vgrinding action on the plate lnot only tends to, but does, wearit.

out, and v,renders it useless lin a relatively `short time.

I have overcome this difficulty by producl ing a counter support plate having an elevated or raised counter supportingportion 11, which, in the plate shown in the drawably vertical, while the outline or perimeter,

of the elevated portion is substantially the same as that of` a counter. The plate lis proary `in .such plates, and the inner edges of the portion 11 areinclined inwardly, so as to e Yform the central depression overA which the counter is located during the finishing op.-

#eration The forward edge 14, of the plate, *fis beveled, with the inclined surface of the bevel grading oli' so that the line between the .surface of the portion 11 and the beveled edge `is not well defined. In addition to this, the edge 14 is curved, so that it is somewhat crescent fshaped,jwith the horns`-of the crescent located at the edges of the plate.v

A strip 15 ofyielding material, such as rubber, is mounted on'the table, in such a position that a portion of its surface is eX- posed through the aperture 12 formed in the plate 8, and the plate is adapted to be secured, by any suitable means, into a way',

Vprovided on the table 6 for its' reception.

The `operation of finishing a counter is late 8 in such a position that its edges register with thevertical edges of the portion 11, as is illustrated in Figs. Sand 4, in conf nectionwith a finished counter 10.- As the table 6 moves inwardly, the clamp 9 engages the rear edge of the counter and Aholds it in place on the portion 11. The roll 7 is preferably so located, with respect to the surface readily engages the surface of the counter supported on the portion 11, it is not capable of contacting with the unraised portion of the plate. With this arrangement the passage of the roll across the plate, during the counter grinding operation, has no detrimental eli'ect whatever upon the plate, since the counter covers and protects l the counter-supporting portion 11 and the remaining portion of the plate is out of contact with the roll.

The roll 7 is preferably, but not necessarily, made of some non-abrasive material, such as compressed felt 23, and with the abrasive or grinding surface 24 extending only partially across its cylindrical face, so that the non-abrasive ends 25 and 26 of the roll are exposed. The rollis also preferably mounted so that its bearings 27 and 28- are capable of moving or yielding vertically under the infiuence of springs 29 and 30, when engaged by the plate, and the beveled ed e 14 of the plate is so arranged that its ends will engage the non-abrasive portion of the roll and in this way raise it to the proper grinding, or counter-engagin position. Under these conditions the a rasive surface of the roll has little opportunity of contactingwith the surface of the plate during the forward motion of the table 6.

As the table 6 moves forward, during the grinding operation, it rst moves the countravel of the table.

ter, located on the plate, under the roller 7, and then moves a rack 16, ycarried by the table, into meshing engagement with a pinion 17, which is 'mounted on a pressure roller carrying arborv 18. The arbor 18 is journaled in arms 19, which are yieldingly heldv against a stop 20, on the frame, by means of a spring 21, and the pressure roller mounted on the arbor 18 is adapted to move into engagement with the counter located on the plate, and to hold it in place after the clamp 9 has moved to the releasing position. The pressure roller also aids in delivering the counter through a chute l22, with whic the machine is provided, after the counter is ground. v

As soon as a counter is finished anddelivered from the machine, the table 8 moves back to the position shown in Fig. 1, Ain which the plate 8 is adapted to receive another counter to be ground. This backward motion of the table is accomplished very rapidly, and consequently, the abrasive action of the roll 7, on the elevated portion 11, has little detrimental electeven though the roll ackward means are not employed for raisin 7 free of the plate during the In 'accordance' with the United States l patent statutes, I have illustrated and decounter-supporting portion.

scribed what I now consider to'be the preferred embodiment .of my invention, but I desire it to be understood that various changes, modifications and substitutions may be made in the ap aratus illustrated without departing. from t e spirit and. scope of my invention as set forth by the appended claims.

What I claimis:

1. A support plate :for 'counter finishing machines, ,provided with an elevated counter-supportin portion, with an outline substantially similar to the outline of a counter adapted to be supported thereon, and having a curved forward edge, vwhich isinclined at a relatively small angle to the surface of the se 2. A support platefor counter finishing machines, having a curved and beveled forward edge and being provided with an elevated counter-supporting surface, which ter- 3. In a machine of the character described, a reciprocable table, a grinding roller normally vbelow the level of a counter support plate located on the table and capable of yieldingx vertically, with relation to the table, and aving a non-abrasive por-` tion, a counter support lplate mounted on the table land having a projection formed thereon for engaging the non-abrasive portion of the roll and for thereby raising the p roll to engage a counter located on the plate. v

4. In a machine of the character described, a reci rocable table, a grinding roll capable of yie ding vertically, with relation to the table, and having non-abrasive ends, 100 a plate mounted on the table above the normal level of thel roll and having a curved forward edge for engaging the non-abrasive ends of the roll and for raising the roll to a counter-engaging position.

5. In a .machine of the character described, a yielding grinding roll rotatably mounted on the machine, a reciprocable table movable under said roll, a plate mounted on the table and havin an elevated countersupporting portion ormed thereon and located above the normal level of said roll so that the abrasive surface of the roll is capable of engaging only the elevated countersupporting portion of the plate when the roll is raised by passing the plate under the roll, butis incapable of engaging the unraised portion of the plate.

In testimony whereof, I have hereunto subscribed my name this 31st day of May, 120 1913.
